Vithin the rod is brackets are identical in form and a descripa locking device 6 formed by a resilient wire tion ofone will suffice for both. The bracket strand 'bowed into substantially U form and comprises a'ibodymade of a single sheet metal tending to expand within the rod. Thefree blank forming a flat portion 16 having ends of the wire strand are bent outward for straight parallel edges extending mostlooking engagement with the keeper notches of its length. At its outer end said and'formed withprojecting loops 7 which are flat portion is widened and formed with a manually engageable for compressing "the pairofspaced, rearwardly turned books or an strand out of engagement with-the notches. barbs 1mm anchoring to'an outer side of the r Two tension springs 8 are anchored at one lwindowiframe; A rod-supporting ear 18 is gaging the straight-edges of the flatbody por- 7 tion and shiftably holding'the slide thereon.

At its end adjacent the ear 18 the slide has an integral, forwardly turned, rod-supporting ear 21 of less lengtl'i than car 18. A tension spring 22 is anchored at one end to anoutstruck tongue 23 upon the body of the bracket and adjacent the ear 18. The opposite end. of the spring is anchored to the inner end of the slide, and the spring extends-through atubular housing 24- formed byibending the slide outward along a longitudinal medial line. The spring tends'to draw-the slideiontward toward the ear-r18. If desired, the slide and spring maybeomitted from one of the brackets and the ear 211 may be. carried directly-by the body of the bracket.

Each of the cars 18 and 21 has a pair of bayonet slots 25* for receiving the projectrod ends; The slots extend rearward from the forward edge of. the; ear' and then vertically in opposite directions to form recesses 26 for receiving the pron-gs. The'slotted ear .forms twoopposed hook-like keepers for holding the prongs, and the hooksare separated by a tongue 27. The entrances of the two slots 25 are materially closer together than the normally expanded prongs and-to mount the prongs one of them is first inserted transversely into its keeper recess, as indicated in Fig; 8,a=nd then the prongs are compressed to permit the other prong to pass-into its slot to its keeper recess, whereuponthe resilient prongs expand into holding engagement in their keepers. The keepers hold the prongs against lateral displacement and the loops 15 engagethe-ear to anchor the prongs against endwise withdrawal. For the detachment of the-prongs from the ears, the rod may beforcibly'depressedto bend the lower prongs and shift the upper prongs into register with the entrances of their slots." Then, the rod mav be rocked and lifted freeof the ears.

Or, the loops 150i the prongs may be grasped tormanually compressing them. The'tongue 21' limits compression of the prongs-..

The: drawings show the rod R anchored to the longer ears t8 and another rod H similarly provided with supporting prongsanchored to the shorter ears 21. The rod R is similar to the rod R except-that the resilient locking device is fixed to the inner rod section 2, instead of anchored" thereto by a; spring. \Vhen the rod. R is anchored in place the tension: of the springs 22- holds the barbs '17 of the brackets in anchoring engagement with the WIIIdOW frame: The tension of the v springs in'the: outer rod R also acts to hold ance of its-springs to reach the ears 18.

It will be seen that my invention provides a secure support for curtain rods and at the same time enables them to be readily mounted and deinounted- What I claim is:

1. *Tlie combination of a-curtain rod ra pair Lot spaced supporting prongs carried by said rod, extending trom an end thereof and comprising resilient shanks having enlarged anchoring heads at their outer ends; and a supbracket for the rod includinga pair of vertically spaced hook-like keepers for the prongs, opening toward each other and having entrance: clearance therebetween more 1 contracted than the normally expanded p ron g ing'. shanks of the resilient prongs upon the 'prong' shan'ks into said recesses, the prongs being compressible toward each other for insertioninto the recesses and resilientlyjexpansible for holding engagement therewith.

3. The combination ot a curtain rod a sub stantially U-shaped resilientinember secured to an end. of said rod and fonning' resilient prongs extending longitudinadly' from. an. end of the rod and having enlarged; anchoring ends; and a supporting bracket for the rod including means defining a pair of spaced keeper recesses opening toward each other and clearance for transverse insertion of said prongsinto said recesses, the prongs being compressible toward each other for insertion into the recesses and resiliently expansible into holding engagement therewith.

6. An extensible curtain rod comprising a plurality of rod sections connected together for longitudinal relative shifting; a locking device shiftable longitudinally of the rod; a tension spring extending longitudinally of the rod and anchored at one end to one of the rod sections and at its opposite end to said locking device; and keepers carried by the other rod section at spaced points therealong and releasably and selectively engageable by said locking means for shifting the spring anchorage and varying the rod length, the rod being extensible against the spring resistance when the locking device is locked.

7. An extensible curtain rod comprising aplurality of rod sections connected together for longitudinal .relative shifting; a locking device shiftable longitudinally of the rod; a

8. An extensible curtain rod comprising a plurality of rod sections connected together for longitudinal relative shifting; a resilient, snap locking device adjustable longitudinally of the rod; a tension spring extending longitudinally of the rod and anchored at oneend to one of the rod sectionsand at its opposite end to said locking device; and keepers of ratchet'form' carried by the other rod section at spacedpoints therealongand releasably and selectively engageable by said locking means for shifting the springan chorageandvarying the rodlength, the locking device being shiftable inward with said spring-anchored rod section andover said ratchet keepers to shorten the rod and being positively lockable automatically to the keepers'to anchor the'spring for yieldable resistance to extension of the rod and manually releasable to permit free extension of the rod.

9. The combination of a curtain rod; a pair'of spaced supporting prongs carried by said rod and comprising resilient shanks extending longitudinally from an end of the rod and having enlarged anchoring heads at their'outer ends; and a supporting bracket for the rod including a forwardly extending ear having bayonet slots with vertically spaced entrance branches extending inward from the forward edge of the ear and keeper branches extending upward and downward in opposite directions, said entrance branches being closer together than the normally expanded prong shanks and said shanks being compressible toward each other for transverse insertion into said slots and resiliently expansible into holding engagementwith the keeper branches. 7
